Abstract:
A system, a method and an apparatus are described. The apparatus comprise a modem that determines frequencies at which a transceiver of a wireless device is susceptible to interference generated by a different transceiver of the wireless device, and that modifies a search for a radio access network based on the one or more frequencies. The first transceiver may be susceptible to the interference by means of transmission of the interference through one or more circuits within the wireless device. A threshold power level may be modified based on an estimate of the power of the interference. The threshold power level may be used to determine presence of a pilot signal. The interference may be modeled based on a list of frequencies associated with one or more subscriptions of the wireless device. An order of searching for pilot signals may be modified.
